Extraction of Iron

The present invention relates generally to production of iron (III) oxide. More particularly, the invention relates to production of iron (III) oxide via recovery, purification, extraction, separation and/or isolation from various iron-containing ores.

BACKGROUND OF THE INVENTION Several well-known forms of iron oxides are provided naturally in essential ores such as magnetite, hematite, goethite, limonite, siderite,....etc. Iron (III) oxide has received and still receiving much attention, not only on the industrial level but on all known economic and strategic levels, since it is mainly applied in the iron and steel manufacture. Moreover, it is considered as one of the most important materials utilized in other industries such as ceramics, glass, paints, rubber, plastic, paper and building materials industries, and more.
